My Thunbergia started coming on good by the end of August.

These were two different varieties. The Sunny suzy 'rose sensation' had more numerous leaves than the 'red orange' and those hid a lot of the red/pink flowers. I'd probably plant just one variety in the future. Both these types have permeated the entire trelis from end to end and overwhelmed the flower bed at the bottom.

Even tried to take over the inside of garden shed, dark as it is in there. 🫤
